Digital Business / Business email / Team workflows
Use an email alias when one person needs another address in an existing mailbox. Use a shared mailbox or delegated inbox when several people need to read and answer the same business conversations. Use a distribution list when the purpose is to deliver a message to several recipients, rather than manage a shared queue.
The address alone does not reveal the setup. [email protected] might be an alias attached to the owner’s mailbox, a team mailbox, or a list that distributes copies. Choose by who must do the work, what history they need, and how responsibility will pass to someone else.
When a customer replies tomorrow, can the right colleague see the full conversation, know who owns it, and respond using the intended business identity? An address that receives mail is only the first part of that workflow.
01 / Compare alias, shared mailbox, and distribution list
An alias is an additional address associated with an existing mailbox. A shared mailbox gives authorized people access to a common mailbox. A distribution list delivers messages to its members. These solve different problems even when all three can use a familiar role address such as [email protected].
| Option | A sensible use | Main limitation to consider |
|---|---|---|
| Email alias | One person handles several public-facing roles. | Another address does not create an independent team workspace. |
| Shared mailbox or delegated inbox | Several authorized colleagues handle one business address. | Access, sending, history, and ownership still need configuration and rules. |
| Distribution list | Notifications need to reach a defined set of people. | Delivered copies do not by themselves establish a shared response queue. |
Microsoft’s group comparison distinguishes distribution groups for notifications from shared mailboxes for common addresses. It also describes Microsoft 365 Groups, which provide a broader collaboration workspace. Avoid assuming that every feature labelled “group” is the same type of inbox.
Start with the work: “everyone needs this announcement” and “someone must answer this customer” are different requirements. A team may need both a notification list and a separate customer-facing inbox.
02 / Use an alias when one person owns the work
An alias can give a solo business distinct addresses for enquiries, billing, and sales while keeping delivery in one place. Google Workspace’s alias documentation explains that mail to a user’s alias arrives in their primary inbox. Its aliases belong to one user and are not separate Google Accounts.
A freelance designer handles every enquiry and invoice. They use [email protected] for enquiries and [email protected] for invoices, both attached to their own mailbox. Labels or folders keep the work organized. There is no second colleague who needs separate access or an independent queue.
Receiving at an alias and sending from it are separate checks. Confirm the supported outgoing setup, then send a test message and reply to it from an external account. Inspect the visible sender and reply destination. Gmail’s send-from-another-address guidance treats the From and reply-to settings separately.
Reconsider the setup when another person regularly covers the role, when business history is mixed with personal work, or when someone must leave without disrupting the public address. More aliases will not resolve unclear responsibility or make a personal inbox suitable for a whole department.
03 / Use a shared inbox when continuity matters
A common mailbox can keep business correspondence available to the authorized team instead of leaving the working history in one employee’s inbox. The practical benefit is continuity: another colleague can cover an absence, review an earlier answer, or take over a request.
A small shop has two people answering [email protected]. Forwarding each message to both employees gives them copies, but neither automatically knows whether the other has replied. A common inbox, visible outgoing history, and a clear ownership rule better fit their work.
A shared inbox still needs an operating agreement. Decide who checks new messages, how someone claims a conversation, when it is finished, and who checks unattended work. Simply giving everyone access can leave each person assuming someone else is responsible.
Write down a small set of statuses, such as new, assigned, waiting for the customer, and complete. Implement them using the features the selected service actually supports. If assignment, internal notes, collision warnings, response reporting, or escalation deadlines are essential, make those explicit requirements when comparing a dedicated help desk or shared-inbox product.
04 / Check what your provider means by “shared”
Microsoft 365 shared mailboxes
Microsoft provides an Exchange Online shared-mailbox model. Its shared-mailbox documentation states that a mailbox can store up to 50 GB without a separate mailbox license, while each accessing user needs a licensed Exchange Online mailbox. Larger storage and certain archiving, hold, or advanced features can introduce additional licensing requirements.
That is not a promise that an entire team email system is free. Verify the users’ subscriptions and the exact features required. A plan containing office apps should not be assumed to include the necessary hosted email service.
Google Workspace shared inboxes and delegation
As checked on 23 October 2026, Google’s Create a shared inbox guide lists Business Starter, Business Standard, and Business Plus as supported editions. It describes an administrator-created mailbox with delegates who can read, send, and delete mail. Google says the administrator feature is being released in phases and points users to delegated Gmail accounts if it is not yet visible.
The same guide describes sender information showing the shared address and the delegate, with settings affecting whether the delegate information is visible. Check that presentation against your business’s requirements rather than assuming every reply conceals the individual sender.
Google’s separate delegation guide explains access to an account and notes that an alias itself cannot have delegates because it is not a Google Account. Confirm licensing for the actual mailbox and users with your administrator or supplier; do not apply Microsoft’s licensing model to Google.
Google Groups Collaborative Inbox
This is another option with a different workflow. With suitable permissions, a Google Groups Collaborative Inbox lets members assign conversations and search by assignment status. Evaluate the Groups interface, posting permissions, external-sender access, and response handling with the people who will use it. It should not be treated as an identical substitute for a delegated Gmail mailbox.
05 / Verify access, sending identity, and reply history
Test these separately. Someone may be able to read a mailbox without having the required permission to send as it. A successful reply may also be stored somewhere the other members do not routinely see.
Microsoft’s shared-mailbox creation guide distinguishes Full Access from Send As and Send on Behalf permissions. Full Access alone does not grant sending rights. Send on Behalf can also present a different sender identity from Send As.
Microsoft’s configuration guidance says shared-mailbox messages are saved by default in the sender’s Sent Items rather than the shared mailbox’s Sent Items. Administrators can configure the shared mailbox’s sent-item settings. Verify the resulting history using the clients your team actually uses.
Give people authorized access through their own accounts. Microsoft’s creation guidance says new shared mailboxes have direct sign-in blocked by default. Use the provider’s supported delegation or membership model, and keep an inventory of who has access.
Do not place unrelated private correspondence in a mailbox that several employees must open. Set the scope before granting access, particularly when financial, personnel, or other restricted conversations are involved. Review memberships when responsibilities change.
06 / Compare the complete cost and workflow
Count more than public addresses. Ask the supplier to price the real arrangement: people, mailboxes, storage, required controls, and any collaboration software. Google’s alias guidance, for example, describes aliases available without an additional alias charge for an existing user; that does not make them equivalent to separately provisioned team accounts.
| Check | Question to resolve |
|---|---|
| People and licensing | Which users and mailboxes need subscriptions for this exact configuration? |
| Access | Can each authorized person use their own account on the required devices? |
| History and retention | Where are replies stored, and what happens to messages when someone leaves? |
| Work ownership | Can colleagues see assignments and completed work, or is another tool needed? |
| Limits and extras | What storage, archiving, support, security, or reporting features add cost? |
| Exit | Can you retain the address and export the correspondence if you change providers? |
Compare the annual commitment and renewal terms, not just an introductory price. Our small business website running-cost guide places business email alongside the other subscriptions a business needs to budget for.
Choose a system the team can operate consistently. A sophisticated assignment feature has little value if everyone continues replying from disconnected personal copies. Include a short demonstration using a realistic enquiry before making a longer commitment.
07 / Test the setup and plan for staff changes
Before publishing a new address on your website, run a controlled end-to-end check. Use test messages without customer-sensitive information and record where each message and reply appears.
- Receive: send an enquiry from an external mailbox and confirm it reaches the intended destination.
- Open: have each authorized colleague access the inbox through their own account.
- Reply: check the external recipient’s view of the From address, sender information, and reply destination.
- Continue: ask a second colleague to locate the conversation and its outgoing reply.
- Assign: demonstrate who owns the request and how completion is recorded.
- Cover: simulate the usual owner being unavailable and confirm another person can continue.
- Remove access: verify that an administrator can remove a departing member while retaining the business address and required history.
If the address currently exists as an alias, list, or mailbox, plan the transition with the administrator. Do not delete the old destination before deciding how existing correspondence and new arrivals will be handled. Recreating an address elsewhere does not by itself move its historical messages.
If you also change the email provider, separate that project from the inbox-choice decision. Our domain transfer vs DNS change guide explains why registration, DNS, hosting, and mail services should be planned separately.
Finish with a named business owner for the address, an access list, a cover arrangement, and a brief operating procedure. Those decisions matter as much as the address printed on your contact page.
Frequently asked questions
Can several people share an alias?
An alias does not itself create a team workspace. In Google Workspace, a user alias belongs to one user. If several people need access to a mailbox receiving role-address mail, evaluate the provider’s supported shared-inbox or delegation model.
Is a shared mailbox the same as a help desk?
No. A common mailbox provides shared access, while a help desk may supply additional workflow features. List the capabilities you require—such as ownership, internal notes, escalation, or reporting—and verify them instead of relying on the product label.
Should a solo business start with aliases?
They can fit when one person owns every conversation and the shared history or access requirements are simple. Reassess when another person regularly covers the work, responsibilities separate, or the business needs a more structured queue.
